I have the opportunity to buy a Ninja 300 bar Carbon composite bottle 90 CUI (about1,5 liter I rate).
Does anyone have one or have seen these bottles?
This one was manufactured in 2013 so it should be hydro'd now again though, but the bottle should be good for another 10 years as carbon bottles last only 15 years.
Ninja had a factory fault where the outer gel layer cracked because of the expansion and contraction of the bottle but it is believed to be only cosmetic and if the hydro holds up it should be fine?
I watched a YouTube video and it seems like these bottles will be able to fill my Beeman Qb79 converted to HPA, about 8-10 times that's all I need really.
